1. SDI journal Web sites provide the ability for users to comment on articles to facilitate community evaluation and discourse around published articles. Comment section is mainly dedicated to promote "Post-publication peer review". Therefore, all SDI journals strictly follow 'pre-publication OPEN peer review' and strongly encourage "Post-publication peer review". As a result of this "Post-publication peer review", if authors agree and or journal Editors agree (and or SDI agrees) that any correction is necessary, then it will be published FREE of cost by following SDI Correction and retraction policy (http://www.sciencedomain.org/page.php?id=sdi-correction-and-retraction-policy).
